UNITED LIFT-PUMP..

Specification of Letters loatent.

latenteol April 3, 1906.

Application filed May l, 1905. Serial No, 258.239.

Be it known that I, HERBERT MONTGOM- ERY Onow, a citizen of the United States, and a resident of Oakdale, in the county of Stanislaus and State of California, have invented a new and Improved Lift-Pump, of which the following is a full, clear, and exact description.

This invention relates to lift-pumps, such as are used for raising water from wells.

The object of the invention is to provide a pump which may be driven by means of an engine or similar' motive power, but which is adapted to be altered readily, so as to enable the well-rod to be attached to the rod of a windmill.

The invention is especially useful in those localities where windmills are used for raising water, but which cannot be depended upon under all weather conditions.

The invention consists in the construction and combination of parts to be more fully described hereinafter and definitely set forth in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all th igures.

Figure 1 is a side elevation showing a pump in its normal condition, a portion of the pipe leading from the well being represented as broken away. Fig. 2 is a side elevation of the pump-cylinder and represents the same as connected with a windmill-rod, certain parte being broken away, as will appear; and Fig. 8 is a vertical section taken through the coupling with which the drivingrods are connected.

Referring more particularly to the parts, 1 represents the pump-cylinder, which is preferably expanded below to form a base 2, resting on a platform or similar support 3. The piston 4, which passes upwardly from the pump cylinder is reci rocated in the usual manner, so as to enaole the pump to raise water through a pipe 5, leading from the well.

Vertically above the pump-cylinder 1 and in alinement therewith I provide a cylinder 6, which is preferably a steam cylinder, which operates to reciprocate the piston 7, which projects from the lower head 8 thereof. This cylinder is supported upon legs 9, which are bowed outwardly, as indicated in Fig. 1.

These legs are formed with scarf-joints 10, dividing them into upper sections or legs 11, which extend downwardly from the head S, and lower sections or arms 12, which extend upwardly and are integral with the pumpcylinder 1. The scarf-joints 10 are formed with shoulders 13, which operate to increase the security of the joints when formed in a manner well understood, The extremities of the legs 11 are disposed inward, as indi` cated in Fig. 1, and these are provided with threaded openings 14, which receive the extremities of bolts 15 which pass through the upper extremities of the arms 12, as indicated. The engine-piston 7 is connected by a a suitable coupling 16 with the pump-piston 4.

The coupling 16 is of any common form, such as that indicated in Fig. 3, comprising heads 17 and 18, which screw, respectively, upon the pump-piston 4 and the engine-piston 7, one of these heads, as the head 18, being upset, as shown at 19, and provided with threads. The head 17 is also upset, as shown at 20, so as to form a shoulder for the coupling-nut 21 to abut against. The interior of this nut is threaded in the usual manner and engages the threads on the upset portion 19 of the head 1S.

l/Vith the arrangement described the engine will of course operate to drive the pump and raise water from the well through the pipe 5 and may be used to raise water to a tank which is placed at an elevation.

If it is desired to utilize the force of the wind for driving the pump, the bolts 15 would be taken out and the engine-cylinder 6, together with the legs 11 thereof, would be removed, the coupling 16 having first been disconnected. The windmill-rod 22 would then be attached by means of the coupling 16, as indicated most clearly in Fig. 2. When connection is made in this manner between the windmill-rod and the pump-piston 4, the actuation of the rod 22 by the wind will of course operate the pump in the same manner as before, and water will continue to be raised from the well and elevated to the tank referred to.

l/Vhile I have described the invention asincluding a steam-cylinder for' driving the pump, the particular motive power is of course immaterial, as I could as well use a gas-engine cylinder or other prime mover.

The invention provides a very simple arrangement for insuring a constant Water-sup- IOO ply under all weather conditions7 the economy to be derived from the use of the wind being utilized as long as the wind blows.

Having thus described my invention, I claim as new and desire to secure by Letters Patent In a lift-pump, in combination, a pump cylinder, an eno-ine cylinder disposed in axial alinement tereabove, a piston-rod eX- tending downwardly from said engine-cylinder, a second piston-rod extending upwardly rom said pump-cylinder, arms projecting upwardly from said pump cylinder and HERBERT MONTGOMERY CROW.
